SANDAL-STRAP-TURNING MAC HINE.

SPECIFICATION forming part of Letters Patent No. 731,182, dated June 16, 1903.

Application filed July 5, 19QZ.

To all whom it may concern.-

Be it known that I, ALBERT H. HIGGINS, of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in- Sandal-Strap-Turning Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a device which is especially adapted to be used in turning the straps which are used on sandals or slippers I after they have been sewed together with the grain side of the leather facing inwardly.

For an understanding of my invention reference is made to the accompanying drawings, in which--- Figure 1 is a side elevation showing my machine in position for use. Fig. 2 is a plan view thereof. Fig. 3 is afrontelevation, and Figs. 4, 5, 6, and 7 are detailed views.

As shown in the drawings, the machine is provided with a table a, which may simply be in the form of a base-plate which is fastened to a bench, and said table a is provided with a vertically-extending standard I), which is firmly secured to said table. The upper end of said standard I) passes through one end of an arm 0, said arm being adapted to swing with respect to said standard. A yoke (Z is arranged on said standard directly above the arm 0, and a pair of rodsfare connected to opposite ends of said yoke and extend downwardly through the table, where they are connected with a foot-lever g. A collar h is adjust-ably secured to the standard I), and a spring 2' is interposed between said collar and arm 0, so that said spring constantly acts to force said arm upwardly. By means of the treadle g the arm may be drawn downwardly against the action of said spring. A vertically-extending standardj is removably secured in the table a, said-standard being flattened and tapered down to a rounded edge at its upper end, so that said end will fit into the tip end of the sandal-strap which is to be turned. A vertically-arranged depending standard 70 is removably secured to the front end of the arm 0, it being cylindrical in form except at its lower end, where it is flattened and provided with a cavity 7t, (see Figs. 4

Serial No. 114,406. (No model.)

and 6,) into which theupperend of thelower standard j is adapted to pass.

An adjustable stop-arm Z is arranged on the standard b above the yoke (1, said arm having a depending portion l' at its lower end, which extends down to one side of the arm 0. Said stop-arm is adapted to be secured to the standard I) by means of a setscrew m, two recesses being formed in the standard b to receive the point of the setscrew, as shown in Fig. 7. When the tip of the set-screw m engages either. of 'these recesses, the depending end Z of said stop-arm will engage one side or the other of the arm 0 when said arm is in such a position thatthe two standardsj and 7c are directly in line.

Having thus described the construction of my device, the manner in which it is used is as follows: The operator first swings the arm 0 either to the right or left away from the stop Z, according to which side of said arm said stop is arranged, to suit the convenience of the operator. The strap which is to be turned is then drawn onto the upper standard It, so that the end of the standard nearly reaches the tip end of the strap. Said arm is then swung, so that it is engaged by the depending portion of arm Z, in which position the two standards will be directly in line, as be foredescribed. Thenthetreadleisdepressed, drawing down the arm 0, so that the two standards come in to engagement at their ends, the upper end of the lower standard j being forced into the recess is in the lower end of the standard k. This acts to turn the tip end of the strap right side out. Then the operator, while continuing to hold down the treadle g, simply pulls the base end of the strap downwardly, so that the strap will be turned onto the lower standardj (see Fig. 4) and will then be turned right side out. Arm 0 is then released and swung to one side, so

that the strap may be removed. After the strap has been turned itis desirable to smooth and straighten it, and this is usually done on top of the standard j, it taking less time to do this than to transfer it to a standard which is solely adapted to be used for that purpose.

From the foregoing description it will be apparent that the machine which I have produced is simple in construction and unlikely t a Y 731,182

tending arm through which said rod passes,

and upon which said arm may swing and slide, a stop on said rod and means for moving said arm against said stop, and for moving it in the opposite direction, a depending standard secured to said arm and arranged to be moved longitudinally in alinement with said fixed standard, a vertioally-extendin g stop at one side of said arm with which the latter engages when it moves-vertically and said standards are in alinement, and means permitting said stop to be fixed at opposite sides of said arm, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
